Return of Ultraman

Kingsaurus III was a dinosaur who survived the extinction and now feasts on nuclear energy and Uranium 235. Appearing on a mountain, it was quickly confronted by MAT and shot down Hideki Go's Arrow 2 with its highly radioactive U-235 beam. Go called upon Ultraman Jack and a fight ensued. Kingsaurus III's barrier quickly reflected all of Jack's attacks, even the Cinerama shot, said to be ten times more powerful than the Wide Shot. After the blocking, Kingsaurus advanced; using his horn beams to blind Jack while stabbing his knee and his waist. Finally, exhausted, Jack collapsed, and Kingsaurus III escaped through burrowing.

In the hospital, Go became horrified of the beast, and later escaped the hospital to train himself to jump over Kingsaurus III's barrier and attack it. After training several times with his broken leg, he finally managed to learn the comet kick and was ready to put it in action. Meanwhile, MAT received a telegram signaling that Kingsaurus III appeared at a nuclear power factory. Go soon followed and tried to jump over the beast's barrier. Failing, he called upon Ultraman. Jack looked at the monster that had defeated him. Calculation led him to conclude that all of Kingsaurus's powers came from his horns. Realizing that, Jack used Go's jump to kick off kingsaurus III's horns. A short beating later, Jack used his Specium Ray to kill Kingsaurus III once and for all.

A distant relative of Kingsaurus III, called Kingsaurus II (キングザウルス二世 Kingusaurusu Nisei?) appeared in chapter 5 of the Ultraman Orb Perfect Super Complete Works 10 Episode Plan.

Sometime in 1908, the tundra area suffered from a large meltdown, foreshadowing the revival of the King Demon Beasts. Kingsaurus II, a monster that was frozen beneath the ground escaped and made its way to the residential area of Lake Baikal. Gai, who was on his way to Rusalka encountered the monster and transformed into Ultraman Orb, fighting and destroying it. The entire battle was photographed by a local aristocrat while Juggler harvested its card to be used in unison with Super C.O.V. and Pris-Ma to unseal Maga-Zetton.


  • Gai's ancient photo in the TV series was also taken by the same aristocrat.

Powers and Weapons

  • Horns: Kingsaurus III has three horns on his face strong enough to stab into the thick hides of Ultras such as Jack.
  • Barb: Kingsaurus III has barbs on his horns, which activate automatically when touched like a jellyfish.
  • Burrowing: Kingsaurus III can burrow at medium speeds underground.
  • Blinding Flashes: Kingsaurus III can fire blue waves of energy that can repel or temporarily blind his foe.
  • U-235 Beam: Kingsaurus III can fire a light red beam or energy from his mouth.
  • Fence Light Wall (フェンス光壁 Fensu Kōheki?): Kingsaurus III can create a Force field strong enough to stop the beams of Ultraman Jack. However it only surrounds/protects the front of Kingsaurus III and the top is left open.


  • If the horns on Kingsaurus's head are broken off, he becomes completely powerless.
